Troubleshooting a NIC

Last Updated : Jan 23, 2026 |

Procedure

  1. View the server LCD display and System Status LED indicators for error indicators or messages.
  2. Check the appropriate indicator on the NIC connector:
    1. If the link indicator does not light, check all cable connections.
    2. If the activity indicator does not light, the network driver files might be damaged or missing.
    3. Replace cable with known good network cable and view link status.
    4. Use another connector on the data switch.
    5. Check data switch configuration for proper administration.
  3. If iDRAC interface is being utilized, log in to the iDRAC web interface and view status from the System/Network Devices.
    1. Verify NIC status is healthy and view individual NIC port state, statistics and configuration. Verify information is consistent with intended installation. That is, Enabled, Link status, Protocol, OS state, port statistics, and so on.
  4. Ensure that the NIC is configured correctly in KVM on RHEL 8.10. Refer to Installing the Avaya Solutions Platform 130 Series R6.0.x.
  5. Ensure that the Avaya Solutions Platform 130 server NICs and data switch ports are all set to the same data transmission speed and duplex.
  6. Ensure that all network cables are of the proper type and do not exceed the maximum length.
    Note:

    • Customers must supply cables and/or transceivers compatible with their network infrastructure.

    • For 1GbE interface, always use 1000BaseT UTP (CAT5e) cables as a minimum or 1000BaseTX UTP (CAT6) cables.

    • For 10/25GbE interfaces the appropriate transceivers and cables are dependent on the customer network infrastructure. Proper cabling (fiber optic or Direct Attach Copper [DAC]) and compatible transceivers are required to operate the 10/25 GbE interfaces. These interfaces use the industry-standard Small Form-Factor Pluggable 28 (SFP28) form factor. Customers must select cables and transceivers that are supported and qualified by their respective network switch vendor. Refer to the switch vendor’s documentation for the approved SFP28 cables and transceivers to ensure compatibility and correct operation.

  7. Perform the following steps for additional debugging:
    Note:

    A keyboard and monitor is required to connect to the server console.

    1. When feasible, reboot the server according to Avaya’s application instructions.
    2. From Dell console, press F10 to go to Lifecycle controller menu and run the diagnostics from the console.
    3. Select Hardware Diagnostic > Run Diagnostics.

      This begins the testing of a server. You can abort the testing to select specific component by pressing ESC.

    4. Select network interface for testing and view results.

Next Steps

If the part is defective, continue with the removal and replacement procedures.
